COOKING-LSTOVEQ Specification forming part of Letters Patent No.103,306. dated May 2 1870.

To allwhom it may concern.-

Be it known thatwe, WILLIAM C. DAVIS and J onN W. GARRISON, both ofCincinnati, Hamilton county. Ohio, have invented a new and usefulGook-Stove, of which the following is aspecification.

The fire-grate of our stove is divided horizontally. The lower member,when used for coal,consists of a shaking and dumping basket, and isreplaceable by-a wood-burning hearth, to which the upper part of thegrate serves as a fender.

In the drawings, Figurel is a perspective View of a cook-stove embodyingour improveplace-as adapted for coal and for wood, re-

spectively. Fig. 7 is a perspective view, to a larger. scale, of ourcoal-grate. Fig. 8 is a similar viewof the "wood-burning hearth orbottom.

That portion of the stoves front plate in front of and'below thefire-grate has a bonnet or protrusion, A, which slopes outward anddownward, in the manner shown, in order,

, without encroaching upon the oven -space, to

permit the forward dumping of the grate, as hereinafter explained, andatthe same time to afford sufficient opening for the free discharge ofashes' The upper portion of the bonnet A has an opening, a, which isjclosable at will by a door, B, whose pivots 6 rest in hooks O, thatproject from the bonnet, which pivots and hooks coact with lugs D tohold the door in the represented horizontal position when open, so as toconstitute said door a shelf orhob for the purpose of holding a dish orpan. The door B, when closed, rests against the sloping front of thebonnet, and is thus, whether closed or open, held in position by itsgravity, but, for additional security, may be held to its closedposition by customary latches, E; The said fire-door may also be Ipierced with draft-apertures f, closable by a register, F. The frontoven-plate should slope forward and downward, substantially asrepresented,ands'hould have its upper portion, G, protected by asuitable fire plate or back,

H, which may have the represented ribbed and convex contour toward thefire. The lower portion, G, of said oven-plate, except those portionsnear the jambs, slopes down ward and forward, as shown, was to passdirectly underneath the fire, whose heat it re ceives and transmits tothe lower part of the V oven, and whose ashes it discharges into theash-pan.

Our fire-grate is divided horizontally into two portions or members, ofwhich the upper member, I, is stationary, and serves both for wood andcoal.

When the stove is to be used for burning coal, the lower member of ourgrate consists of a basket, J, composed of a series of bars in verticalplan'es,whose forward portions, 9, are vertical or nearly vertical,while the portions 9', constituting at once the bottom and the back ofthe grate, slope obliquelyupward and rearward to the fire-back H, onwhich they rest. The extremities of the bars 7 j are joined byhorizontal bars j j. pended, by pivots K K, in suitable bearings orsockets in the stove-jambs, the pivot K extending through the orifice Lto the outside of the jamb, and terminating in a square or othernon-circular head, k, to enable the basket to be shaken, or tobe dumpedforward, 7

as shown in Fig. 4, by means of a wrench or key, M, which may have atone'end an eye, m, for engaging with the square head of said pivot, andat its other end a hook, m, for lifting the boiler-covers and otherremovable plates. The pivot K may rest in a-niche, L, on the inside ofthe jamb-plate.

N N are customary end fire-plates.

The two end bars of our basket depend, preferably, somewhat less thanthe others, so as, whenthe fire is low, to gather the combustiblematters to the center, and by approximating a rounded form of cavity tosecure the necessary conservation of heat for active combustion. Thebasket is so formed and supported upon its pivots as to remain atrest,whether in its proper or in its dumping position, and so that when inuse all of its downward rays strike the lower portion, G, of the grate,when the latter is in its proper position for use to gather the burningmatters to the front, and when in the dumping position to The. basket Jis susfreely discharge the same, and to facilitate these functions theportions may slightly overhang, as represented.

lVhen the stove is to be used for wood fuel, the end fire-plates, N N,are first removed, and the basket J, being withdrawn, is replaced by asuitable perforated hearth, O, which rests by lugs 0 0 upon interiorprojections, P, of the fire-chamber, one of which lugs, 0, has avertical position, which serves to close the orifice L in thestove-jamb. The withdrawal of the end fire-plates liberates the endfire-door, Q.

The upper portion of the front plate and the front portion of the topplate unite to form a hopper, B, through whose aperture r in said topplate the-fire is-fed or replenished. The hopper R is closed by a door,1, which is hinged at its rear portion to said top plate.

Draft-registers S may be provided in the upper part of the front plate.

The bottom plate terminates in front in a sink or depression, T, whichconstitutes the ash-pit, fitted to occupy which is an ash-pan, U,(preferably of cast-iron,) having one or more inwardly-projecting earsor hooks, u, to enable the pan to be withdrawn by means of the wrench M.

In order to heat the air of the oven and at the same time to cool thefire-back, we provide, at different elevations in the portion G of thefront oven-plate two series of apertures, V V, through which theoven-air circulates in the manner indicated by the arrows. Ve secureactive draft and combustion and prevent smoke by gradually increasingthe flue-area from the throat W and the neck X.

Y is a warming-shelf to receive a pan or vessel. It may be made withoutopenings, or may be perforated, as shown, so as to freely conduct to thebottom of anything placed upon it the heated air ascending from thestove sides. This shelf may be cast in one piece with the top or otherplate of the stove, or may be bolted or otherwise secured to the stove,or may be simply engaged by lugs 3 which entering notches Z in thejambs, may be held in place by one or more bolts, 2, passing through thetop plate. Brackets y, rest-ing against the sides of the stove, mayassist in supporting the shelf.

The specific forms and arrangements of parts selected to illustrate ourinvention may be variously modified. For example, when designed for theuse of coal exclusively, the grate may consist of a single casting, andthe bonnet Ahave sufficient protrusion to permit the forward dumping ofthe grate as thus modified. Two or more cars may replace the single earor hook in the ash-pan. It will be seen that our grate dumping forward,in connection with the bonneted front, makes a large opening for thepassage of cinders and ashes from the fire-chamber outward, and enablesthe oven to be extended forward under the entire fire-bed, so as tosecure both more space and greater heat for baking purposes, whereas, ifdumped backward in the usual manner, the rear edge of the grate wouldform, with the oven-plate, a contracted throat, liable to become cloggedwith cinders, 850., even when the oven is not extended under the fire;and our grate being separable can be replaced piecemeal as the partswarp or burn out.

e claim as our invention 1. The horizontallydivided convertible wood andcoal fire-grate, having an upper permanent member, I, to receive eitherthe coalbasket J or the wood-burning hearth 0, substantially as setforth.

2. The perforated wood-burning hearth or bottom fire-plate, 0, providedwith lugs 0 0, to support same on projections P, one of which lugs, 0,serves to close the orifice L in the stove-jamb.

In testimony of which invention we hereunto set our hands.
